neomutt gets stuck at sending message

[Chakkramacharya]

I have followed steps twice..and they work perfectly. I got my outlook account configured on it.. But when i send message neomutt gets stuck at "sending message.. "

it gave a gssapi is not a valid authenticator" error in my first attempt and mail gets stuck here..

I searched for gssapi error and got a link saying this issue is closed and to use sasl.. Pl clarify how to use it.. and maybe this should be a part of the installation instructions ?

I am using wsl2 on windows .. ubuntu
Thanks

The error snapshot is attached

Newbie here with terminal based mail clients. I have the same issue with Outlook mail (just says "sending mail") and then stops responding. This is my first time using neomutt and mutt-wizard... Just cannot send any mails and I do not even know where to start! :) Is there some dependency that I need to install to send mail? I made sure I have the msmtp installed...

I ran into this issue aswell when trying out neomutt.
Managed to fix it by switching the port number to the correct one for my outlook account and then setting tls_starttls on in config.

Hi.. Possible to explain in detail or elaborate steps taken to resolve it ?

Yes, I should have been more clear.
I edited ~/.config/msmtp/config
And modified the port from 465 to 587
And tls_starttls from off to on

(I am using smtp.office365.com for my host)
